AM51622C53N-A Equivalent & Substitute Parts

Part Overview

The AM51622C53N-A is a snap-action switch manufactured by Panasonic Electric Works, configured as a single-pole, single-throw normally-closed (SPST-NC) device rated for 16A at 125V AC and 600mA at 125V DC. This chassis-mount switch features a straight lever actuator with quick-connect 0.187" (4.7mm) termination and is designed for momentary on-off applications. The product is classified as obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM51622C53N-A is determined by strict equivalence in the following parameters:

• Circuit Configuration: Must be SPST-NC
• Switch Function: Must be On-Mom (momentary)
• Actuator Type: Must be Lever, Straight
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Quick Connect - 0.187" (4.7mm)
• Current Rating (AC): Must support minimum 16A at AC
• Voltage Rating (AC): Must support minimum 125V AC

The Crouzet 83261643 meets all mandatory substitution criteria. While it features a higher AC voltage rating (250V) and different mechanical specifications, these represent enhanced or alternative capabilities that do not prevent functional equivalence in applications designed for the original AM51622C53N-A.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83261643 is a direct functional substitute for the obsolete AM51622C53N-A. Both switches share identical circuit configuration (SPST-NC), switch function (On-Mom), actuator geometry (Lever, Straight), mounting method (Chassis Mount), and termination style (Quick Connect - 0.187"). Current and voltage ratings are equivalent or exceed the original specification.

The Crouzet part is currently in active production with 1,039 units in stock, compared to the Panasonic part's obsolete status. The Crouzet 83261643 carries RoHS Compliance and REACH Unaffected certifications, meeting modern regulatory requirements. Both parts share the same ECCN (EAR99) and HTSUS classification (8536.50.9040).

Selection of the Crouzet 83261643 is appropriate for applications requiring the AM51622C53N-A where component availability and regulatory compliance are considerations.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83261643 replace the AM51622C53N-A in existing designs?

A: Yes. Both switches are SPST-NC momentary devices with identical actuator type, mounting method, and termination style. The Crouzet part supports the same 16A AC current rating and exceeds the 125V AC voltage requirement with a 250V AC rating.

Q: What are the differences in mechanical characteristics?

A: Operating force differs (120gf vs. 102gf), and mechanical life ratings vary (10,000,000 cycles vs. 1,000,000 cycles). Operating position and overtravel are similar but not identical. These differences do not affect functional equivalence for momentary switch applications.

Q: Is the Crouzet part RoHS compliant?

A: Yes. The Crouzet 83261643 is RoHS Compliant and REACH Unaffected. The original Panasonic part's compliance status is not specified in available documentation.

Q: Are the quick-connect terminals compatible?

A: Yes. Both switches use Quick Connect - 0.187" (4.7mm) termination, ensuring direct compatibility with existing connector systems.

Q: What is the temperature operating range difference?

A: The AM51622C53N-A operates from -25°C to 105°C, while the Crouzet 83261643 operates from -20°C to 125°C. The Crouzet part provides a wider upper temperature range.
